Dynamic Displays Based On User Interaction States

Abstract

A system and method enabling dynamic interaction between users and displays. Interaction states for a user are determined by tracking user motions and position within the field of view of one or more capture devices. Interaction states are defined by any number of factors, including one or more of a user's body position, body orientation. Once a user occupies an interaction state, an associated application layout is applied to a display. Application layout states may include which application objects are displayed for a given interaction state. Triggering an application state is driven by a transition event and a determination that a user occupies an interaction state. Monitoring user motion and position may be performed continuously, so that changes in interaction states can be determined and corresponding changes to application layout states can be applied to a display, thereby rendering the technology dynamic to user movement.
